What Is FORTINET-TRAP-MIB-280?

FORTINET-TRAP-MIB-280 is a Fortinet proprietary MIB defining the SNMP notification (trap) objects sent by FortiGate security appliances running the legacy FortiOS 2.80 firmware branch. Rather than pollable status tables, it is a notifications-only module describing event alerts such as high CPU utilization, along with the varbind objects carried in each trap. Its monitoring role is fault/event-driven rather than polling-based, letting a management station receive an immediate push notification when the firewall's CPU usage crosses a threshold or another defined fault condition occurs, complementing periodic polling of hardware/software health. It is tied to Fortinet's own MIB hierarchy and is version-specific to the old 2.80 firmware, depending on that legacy FortiOS SNMP agent implementation rather than any IETF standard. It applies to legacy FortiGate firewall/UTM appliances still running FortiOS 2.80 in older deployments that have not been upgraded. Engineers can download the FORTINET-TRAP-MIB-280 file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in FORTINET-TRAP-MIB-280. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Fortinet FortiGate firewall/UTM appliances running legacy FortiOS 2.80

Monitoring Examples

No table or scalar object names were captured for this trap-only MIB, but per its stated purpose it defines a notification sent by the FortiGate agent when CPU usage becomes too high, with an accompanying varbind carrying the current CPU utilization value. An NMS receiving this trap would flag the specific firewall as under sustained high CPU load, prompting investigation into a possible traffic spike, attack, or misbehaving process on the appliance.

What Can Be Monitored

  • high CPU usage alert/trap
  • firmware-version-specific fault notifications
